Low trans temps

[j91z28d1]

Was it humming @70mph when you shifted into neutral?

Where are you located? It's wintertime, and cold air helps keep the ATF cooler, longer, while out driving. It's like 35 degrees here and my ATF temps won't crest 100 degrees even after driving 75mph on the interstate for a half-hour.

yeah that's the question. so if it's was humming along, you pop it in neutral and it completely goes. away. even when reved up while in neutral.

that's a interesting one. does the humming change tone or intensity as you're on and off the gas as 70mph? does it kinda come and go at different mph?
